Coldfall Wood - Geology

Geology

The wood lies on the northern margin of the glacial ridge that forms Muswell Hill. The surviving section of the wood lies on London Clay overlain by head. To the immediate west and south this is overlain by gravels of a former course of the Thames, capped by glacial till of Anglian age. It was here in 1835 that N.T.Wetherell discovered a strange mixture of rocks and fossils normally found in the north of England that led to the subsequent recognition of glacial deposits in southern England.
